Research on the machining process modeling of a rotational mold using CAM applications

Rotational molding is a unique process, with a high growth rate, which allows the use of geometries and materials adapted to particular needs. It is superior to other manufacturing methods in terms of low cost, break-even point and size of parts that can be manufactured. Rotational molding products are often a substitute, with a lower mass, for traditionally used materials. In this scientific paper it is analyzed the recent literature related to the field of rotational molding processes. It also addresses the issue of processing a rotational mold, with the main purpose of optimizing the cutting regime. In this context, it is highlighted the way of processing the surface of the outer mold based on deductions of direct observation criteria. The factors considered in this regard are the route, the type and diameter of the tool, the speed and depth of cutting - given that the goal is to achieve a minimum quality of the required surface obtained by technology and a minimum base time. At the end of the paper, the contribution of this research is highlighted along with the arguments presented in support of the statement that this rotational molding process is of particular interest because it has a great potential to meet many surface quality requirements, while reducing cycle times
